Where is the best place to include inc file??

You may include it in any file you want, but you must be sure to not include it within any class or any class' method.

I'd suggest you create a MY_Controller in ./application/core/ and put the 'include' line before you start the description of your MY_Controller class:

Code:

<?php
include('options.inc.php');

class MY_Controller extends CI_Controller {

}

/* File location: ./application/core/MY_Controller.php /*

However, it is much more MVC-/CI-style to create a config file of your configs, put it into ./application/config/your_config.php and have the config file being autoloaded within ./application/config/autoload.php in $autoload['config']. That way it will also be global put you do it in a better way.
You can then access your config-items with

Code:

config_item('status_read');
